Hill tells us that everyone wants to escape from Oz, but the truth is, there is no escape. "Better to stay put, face reality, deal with what you got, and make the best of it. The measure of a man is not where he lives but how. How he makes the best of it."
Why did I just quote that? Because, completely contradicting what he just said, we see Hill getting into a coffin in the morgue and closing it. His wheelchair is nowhere to be seen. Let us never speak of it again -- I know the writers don't. Uch. Worst episode of the series up to this point. By far.
